This article proposes a new infrastructure-free service architecture for the 6G core network. The proposed service architecture aims to reinvent and extend the scope of the 3GPP 5G Service Based Architecture (SBA) with focus on simplification of the overall functional split, low latency of procedures and very high flexibility in deployment and runtime. Leveraging the proposed software paradigm should enable an organic ability of the network to evolve and continuously adapt to changing communication conditions. To address the challenges of implementing the proposed architecture, we present various approaches along with their advantages and disadvantages. A thorough analysis from the network operations' perspective is also presented, clearly underlining how the proposed organic-like evolving architecture has the potential to greatly outperform the current 5G core network one, making it a high potential alternative for the 6G networks.
